Robin I would also vote for the Webster as a starter engine. I have made (making) the Kiwi and I must advise that there are many tricky machining operations not to mention castings which are on the dimensional limit. A mill is a necessarlty. There are however some excellent posts on the...

My 1-2inch mic model number 293-345 has suddenly stopped working giving a blank display. I replaced the battery with a known good cell but no luck. I removed the front cover and verified that the battery contacts were in good condition and making contact. There was no sign of coolant in the...

Ranger - thanks for that link. I have not come across the supplier before and apart from some expensive stuff they have a range of "ceramic" type paints which look very good . I favour spray finishes and I have the equipment. I considered powder coating but its new to me and I therefore...

Thanks Janson. I have concluded that painting is the way forward and I really like the look of "cast iron" paint. Never used it but its now on order. I also have some matt silver paint so I will experiment with that and others. Fortunately blasting gets me back to the start. Thanks for the...

I have some blow holes and a depression in a web on the Kiwi crankcase casting. Normally I would fill this with xxepoxy based compound and when painted it wouldn't be noticed. For this model I would like to have a sand (glass) blasted surface which looks really good but-but-but I have these...

My experience is identical to Emers. eBay is a very convenient supplier of all things including almost any size of screw/socket head. I have found that the sockets are usually oversize especially the smaller grub screws. You just can't torque them up. I now buy from a screw supplier and pay...

Saddo Maybe a little of topic but related to the Warco Minor and I guess similar Grizzly machines. After a few years of light usage the spindle suddenly locked during milling. Reversed the spindle by hand and all was well until it happened again. I removed the spindle and bearings to...

I think posts 29, 30 and 31 are spot on. I to have a round column mill (Warco Minor) with the limited travel quill and find with some initial planning and the use of ER collets/ collet holder that I seldom need to move the head up the column. If I do then I use a laser pointer over 3 metres to...

FYI Macor 6mm dia is approx £40 ($50?) in the UK for 100mm length - ouch!

Thanks George - I missed the picture. Following on from Petertha's post I find chatter a major problem with a single throw crank but with a multi crank like yours I don't understand how you manage to achieve the surface finish shown. Any insights would be helpful Thanks Mike

George Excellent write-up and pics. My question is- How did you get the surface finish and what did the cutting tool look like? In my very limited experience of cranks I have always been plagued with chatter and the inability to have good support for the cutter with its long overhang. Is there...

swarf Other simple ways to reduce size is to send the photo to your computer by email, display the photo and use windows key, shift and the letter "S". you can then use the cursor to capture the whole or part image to the clipboard and then paste it into the post. From the computer you can...

I did consider using silver steel (drill rod) but the sizes available where far from ideal. The steel is also much harder to machine on my little CNC mill. Being a small mill I don't use pumped coolant which also becomes an issue when trying for a good surface finish. Should I have uses...

I suppose you could reduce the urine in a saucepan on the kitchen hob but you would need a good air extractor and probably be living alone with no neighbours! I think I will give it a miss and who needs a smelly compost heap. Beata 1 is the way forward for my small parts. Mike

You know Tim - thats an obvious thing to do BUT I hadn't thought of it. Many thanks Mike

Guys - thanks for your help and I will now "have-a-go" as they say. I will however give the urine process a miss as I am unclear what "a strong" solution means - maybe after a session at the local pub! Thanks again Mike

I have a need to case harden the rocker arms of the Kiwi and I am seeking advice on the "best" process. I have a good supply of propane but I do not have a furnace - just fire bricks. The parts are about 35mm x 7mm x 7mm and machined from bright "mild steel" bar. I don't have the steel ident...

Guys May I make a plea that new posts have a searchable title. The recent post entitled "Hello" was interesting but meaningless when looking at the post listings. Please guys use a title which relates to the content. Thanks Mike

Gordon This is the process I use. Basically you draw a box around the gasket in Autocad, export to Studio and then resize the box and contents to the correct size. In the past I posted the following:- I have been using the Silhouette cutter for many years. Originally using Design Master as...

David It was so good that you reached out (to use an Americamism!). So many people try to struggle along very much in the dark. It has convinced me to make a posting about planning for the future and how to make it easier for those who remain! Best wishes and keep us posted on progress - a...
