Another PeeWee

[e.picler]

Hello to all!
After finishing the Tiny 4 Inline from Kelly, it was a time to start a new project.
I have decided for the PeeWee from Bob Shores, it is 4 cylinders in a "V" configuration.
I have purchased the casting kit a couple years ago from Dirk Tollenaar

With the drawings I got a revised version from Steve Hucks. After studying the drawings, I decided to use Steve version as well as following his instructions/guide for machining the Block

I started on the oil pan following the instructions

TKS,

Edi

I've been waiting for this build Edi, and I'll be following along for sure!

Hi to all!
Some more work done on the PeeWee. That is the block turn.

I clamped down the block to the table flat on the bottom and just touched the peak of the cylinder banks with skim cut.

The distributor boss was just cleaned up for the scribe line

The block was then rotated bottom up and a minimum skim cut taken to clean up the bottom.

The center of the distributor boss was found and transposed to the rear of the block.
The center of the bottom of the block was also found and transposed to the rear of the block and the two points connected.

Faced the bottom to the final dimention

Faced and drilled the the bottom of the center bearing support then installed on the block

Machined the pockets with support in place.

Drilled and tapped the holes for the oil pan

Oil pan installed. Ready for the crankshaf and cam holes

Tks,

Edi

More work done on the block.

Clamped the block on the vise and faced the front of the block leaving 0.2mm for further finishing

Turned the block up and machined the rear surface

Next I clamped the block on a square devise with the front of the block facing up

I used the parallel on the bottom to asure alingment

Next I indicated the bottom of the block to get the conter line of the crankshaft

Than the crankshaft, idller gear pocket and camshaft holes were drilled. I started with a center drill then used a 8mm drill to start and next a 14.5mm drill bit

Tks,

Edi

Nice work, I like it.

[natalefr]

Wow !

 

[e.picler]

More progress on the PeeWee block
After drilling the holes with a 14.5mm drill bit, I used a 12mm end mill to start the idller gear pocket

Using the boring head, I finished the crankshaft, camshaft holes and idller gear pocket

Next I drilled and tapped the holes for the timing cover and water pump

The block then turned over with the back facing up for the final maching block length. I indicated the hole to find the center in order to drill the water passages holes

The following work will be the cylinders holes
I wish to have a better English vocabulary (specially technical) to better explain how I did the maching. I hope the pictures compensate that deficience.

Thanks,

Edi

Nice work Edi, this will turn out very nice after your success with your online 4. Great pictures & they clearly show what you intend.

Keep up the great work!

Hi to all! Thank you Bengt, John and Natale.

I did some more work on the block this weekend, I will post it during this week.
I think I will be able to finish this building faster then the Tiny Inline 4. I have more time available then the previous Project

Tks,

Edi

Hello to all there!
I managed to get some more work done on the PeeWee V4

Following the instructions from Steve, I inserted a 13mm (I'm using metric) rod on the crankshaft hole then I found the center of the cylinder bank and marked 6.5mm each side. Using a square I aligned the side of the rod with the sides of the marks to assure vertical alignment.

Using a pointer, the center of the bank was found

Indicated rod on the front and the back to assure alignment

Machined the the top surface to the proper hight and started the holes with a 8mm drill bit

Next I used a 14.5mm drill bit

Using the same setup I drilled and taped the head holes

Finally the boring head was used to finish boring the cylinder holes and counter boring

The same was done for the other bank

Next I inverted the block on the vise and I indicated the rod to assure vertical and horizontal alignment

The distributor boss was machined to the right hight. After finding the center of the rod, the distributor hole was bored and the PVC hole was bored and taped

That is it for now.
TKS,
Edi

Looking good, nice work

 

[bengt-olausson]

Still looking realy nice.

 

[e.picler]

Thanks Michael and Bengt for the kind words.
I have managed to get some more progress on the PeeWee.
I cut the water jackets, the Bellhousing adapter and the Bellhousing cast

Indicating the cylinder hole to find the center

Using a 16mm x 6mm key cutter, the water jackets was cut. I did not use the rotary table, I just moved the X and Y axis (Steve method)

Here you can see the little pics on the water jackect diameter, because it is not a perfect circle

As my CNC milling control box is under maintenance I had to use the lathe to machine the Bellhousing adapter
I used a 4 independent jaws juck to hold a 68X57X6mm aluminum blank

Then it was finished on the milling

[Brian Rupnow]

Very high quality work. I will follow your build, you are doing a great job.---Brian

Hi to all!
More work done, this time on the Bellhousing
Turning the inside diameter. I have used a four self centering juck

Here I'm machining a light pass between the tabs to give it more uniformity. I moved the juck by hand back forth using a 3mm end mill on the small grinder adapted on the tool post

Using a file and sand paper I finished the outside

Using the same setup the tab holes were drilled

Using the adaptor plate, Ifixed the bellhousing on it to machine the square on its end

And finally I gave a touch on the tabs to correct its irregularity. I fixed a 2mm drill bit on the vise and a 6mm on the drill juck. Moving the bellhousing around the tabs were finished

Here is what I have finished so far

Next I will start the cylinder heads

Thanks,

Edi

Thank you Brian!
Compared to your work, I am still an apprentice.

hello,

can the pee wee v4 block work be done on a 7 x 16 lathe with a milling attachment?

 

[e.picler]

Hello Atkinson!
I think your equipment can do the job without a problem.
Do you have the castings?

Edi

Hello Atkinson!

Do you have the castings?

Edi

Edi,

Yes I have the castings. I have been working on some of the small brass parts. So you think I'd be able to do the milling of the block on my lathe with a milling attachment?

 

[e.picler]

Hi Atikinson!

Yes, I think you will be able to machine the block. The only more dificult part is the cylinder bores but, with a little patience you get there.
Go ahead and just start that. You can count on me if you think I could help.

Good luck!

Edi
