Hey, I got one of those as well! Your Cameron looks particularly minty. Does yours have the two speed motor? See a pic of mine and read my drill bit recommendations in this thread: https://www.homemodelenginemachinist.com/threads/a-micro-drill-press.35630/ I would recommend an Optivisor or...

Bluejets, the sewing machines motors I'm talking about are for industrial machines. They replace a clutch/motor unit so they have tons of torque at low speeds, are self contained and with variable speed at 550W | 3/4 HP. Thanks! That link works fine. Your drill press works great! Definitely a...

The 48DP involute gear cutters are in low supply / high demand so you will have trouble sourcing used ones. I ain't givin' mine up. :p You have a few options to avoid buying new cutters. First, you can go metric (0.5). You can get the whole set (1-8) for the cost of one 48DP cutter with...

Your drill press looks like a slightly scaled-up version of the Cameron Micro drill press. Here's mine: You did a very good job constructing your drill press and the fit and finish is excellent! If it's possible, it would be interesting to see a video of your drill press running. I've been...

It's somewhat disappointing that a topic about model photography only has one picture! 📸 If you going to upload photos onto a forum, remember you don't need to leave it at a 4032x3024 pixel resolution. Yes, most forums will automatically resize the picture, but why push all those pixels around...

It's good to see that your old South Bend found a new home! Sometimes it just takes awhile to find a buyer.

That's something I haven't seen before. Thanks for showing!

Yes, You can get spotting drills in 90, 120 and 140 degree angles. Using a 120 degree point spotter, a regular drill with then be started by the central portion (not the edges) while allowing for the chisel point which should allow for the straightest hole. Having said that, I rarely use...

Your not going to find many people that are working in such tiny sizes with model engines as it's not fun. I curse when I need to drill and tap 2-56 and that's 1.78mm, three times larger than the .5mm you are talking about. If I had to make this part, I would get the shape of the part close and...

How are you going to use a spotting drill for a tiny .4mm (1/64") hole? That's not how you do it for such tiny holes, you use a small carbide bit and punch it through. This is me drilling a .3mm hole in a 3D printer nozzle. Actually widening a .2mm hole to .3mm because blank nozzles seem to...

Does a rusty tank leak or explode? The explosion idea comes from the 3rd post of this thread, but as shown the owner of that air compressor performed his own poorly thought-out repair on the tank. He had no idea what he was doing and he should have scrapped the tank when it started leaking. From...

For my uses, I have a nice digital Mitutoyo 6" caliper for all the reasons you state. It's my most used metrology tool, so I don't mind the battery use (they last a few years anyway) and it's also one of the few tools I bought new. Almost all the other measuring tools I have were bought used...

Attached are the drawing notes to go with the Kerzel engine plans Rdean33422 posted.

Did they actually repair the mic or did they just send you a new one? Sometimes it's cheaper for the manufacturer to just replace the mic, but then again these are expensive enough to warrant the effort. Over here, that's a $220 mic from a reputable dealer. When buying you gotta watch because...

Looking good! That key came out well. What I do when I broach a keyway with a bottle jack press is use the press and release method. Start broaching the keyway, release the pressure on the broach and then press again. Do that a few times until the broach is well seated in the bushing and you...

McMaster-Carr is a major industrial supplier for the USA. While they usually aren't the cheapest, they stock a LOT of items and they also have an extremely good website. They also sell various styles of ASME air tanks including stainless steel tanks...

Great job! That Hoglet is running really well. Is that a small motorcycle starter?

If you are looking for ideas, here's two completed V-Twin builds on Youtube: Among other things, the fuel delivery system is different between the two builds as the one uses a pump to move the fuel up to the carbs while the other relies on the high fuel tank. It's great to see your engine...

There's your problem! Not a factory weld. According to the guy who filmed the video, after 10 years the tank developed pin holes around the drain even after he drained the tank every day! Sure, OK, whatever. Rather than scrapping the tank like a sane person, he decided to cut the old drain...

This is an interesting thread. I suppose the easiest way to perform this operation would be using a horizontal mill and something like this: With the correct arbor it would make the cut easily. Two drawbacks: First you need some HP to effectively use this tool as horizontal mills have arbor...
