Thread: Your latest project

Started this thing a while back and never got around to finishing it. It's mostly finished but I will make some modifications to it as I am not overly happy with the tool post. It was a miserable attempt to copy Anorak Bobs design regarding the tool post. I was orignally going to make a fixed tool height and use a carbide insert but saw the benifits of a tool post that could take any number of HSS bits.

Still have to make the handle. The radius adjustment can be made using an M6 leadscrew and a brass knob but I have since found that it gets in the way of the chuck so I won't be using it.

The design is a combination of designs I found on the net and also worked around the constraints of the material I had, which started out as a cast iron hand weight which I picked up at the local market for about $6.

Yet to make some balls though.

that was very nice of you to make mine first...

at least you'll know yours will be perfect after critical examination and testing of the demo model

I think you'd be selling yourself short if you took this one Eskimo!

Some time ago I had the need to do a small milling job in my lathe. I got by, gripping an endmill in the 3 jaw chuck.

More recently I decided I needed something a bit better so I made a D1-6 ER32 collet holder.

The cast iron D1-6 backplate came with my lathe. The collet holder was made from mild steel plate welded to a 4140 shaft. I TIG welded them using 309 SS wire. The nut was purchased along with the collets.

It was a useful exercise. I utilized slip fit, shrink fit, welding, threading, and taper turning on the one job.

A quick test run this afternoon went quite well.

Okay then...I will wait till next week for the improved model...no?

Hi All
I thought about posting this as a "Can you identify this tool" but thought it would give Stuart a sore head. As you can see it is a Archery Bow Vise. I have needed one for quite a while and finally got around to drawing it up and making it. I had all of the materials on hand, could have done with a little bit longer piece for one of the members as you can see I had to rebate one piece to accommodate a dome nut.Like all vises it allows me to have two free hands to work on the bow for maintenance etc.and it portable. Machining the two radius ends gave me the opportunity to use the Meca rotary table that I obtained a while ago, quality tools are a pleasure to use . As the photos show I can rotate the bow to any position and hold it firmly, making all of the adjusting nuts the same size only requires one spanner.

I have learned to never underestimate Stuarts superpowers...

Nice work, is that so that in quite a few years time, (old age) you can still shoot a bow. Is it made from aluminium?

Remind me never to make yo angry!

Stuarts superpowers truly are amazing.The vise body is made from aluminium and fittings from stainless, as you get older you can adjust your bows weight down. The big advantage with Compound bows is that the holding weight can be as low as 20% of the bows actual weight. Makes it a lot easier for old guys like me.

I was aware that the cam action made the holding force considerably less than the release force (for want of a better term) but didn't know it was that much less. That is significant. Nice work BTW.

Simon

Hi Simon,
The let off is controlled by the cam/cams design. With the variety of bow/cam designs available today you can have from 50% to 80% let off. Most bow hunters choose the 80% as it allows them to hold at full draw and wait for their prey to move into view without them moving at all. I shoot Target style and have a 65% let off as this extra holding weight works better with a release aid for more accurate shooting.

I am late catching up, I know. I mentioned my desire to do this for ER40 not too long ago. I had been looking for a D1-6 backplate, then I saw my drive plate one day. That is what I will use. Good Job.
