New lathe, still on packingcase base.
New lathe, still on packingcase base.
Making tool holder. Pack up tool post by 1/2 the thickness of tool steel bit, cut slot. This will make tool top surface on centre line.
Modified parting tool holder. I welded a piece of rectangular section keysteel on to side so that top of toolsteel is on centre height. The support out the front makes parting very rigid and easy. Best modification ever :) :)
Boring bar holder for 1/2" shank bars was drilled insitu so that when the boring bar is put in it is on centre. There's the finished tool holders, and as I hate stuffing around with packing they've been made so the top surface of tool is on centre.
This packed out safety strap allows you to park the tailstock that little bit further out for more elbow room.
Boring bar holder for 1/2" shank bars. The holder is two pieces of keysteel welded together. An advantage of having the boring bar out from the toolpost is that it will reach the centre line of the lathe even when the compound slide is located in the position closest to the operator.
Original full circle degree ring was only secured(rather loosly) by 3 screws. I added 3 socket head cap screws and drilled and tapped as deep as I could go. This mod made compound slide heaps more rigid. I also added 2 nip up screws on compound slide, really handy.
You can see the two places for compound slide.
Yep 4" across.
Parting piston with u-beaut parting tool.
Original saddle clamp. It used to twist around on an angle when tightened and the back adjuster screw was useless.
Modified saddle clamp.
Modified saddle clamp 2nd view.
Modified lock plate in place. No more wriggling around or twisting on tightening.
Modified tail stock. Spring and end brackets stop clamp plate from jambing when moving tailstock. I fitted adjustable stop to front of tailstock to stop from clashing with cross-slide gib adjusting screws or my nip up screws on cross slide.
Left side saddle chip tray, mymod.
Right side saddle chip tray, mymod.
Modified splash guard to close up gap that was there exposing end of motor. I also made better clearance for saddle to come closer to headstock without clashing.
Closer view of previous pic.
Dialling my drill to see if machined nose is true to axis. Yes it is within .002" TIR.
Fabricated steel bracket was bored in situ to suit drill.
Close up of my cross-slide nip up screws.
Putting lathe on my home made stand with my spacers under lathe bed. You can also see that I have removed the empty tin box at left end of leadscrew, with this removed the saddle will come closer to the chuck end.
In place on stand. I will soon have shelf in place and fully enclosed with 2 doors.
End View. I have now to modify splash guard to reach down to chip tray.
Castor and jack screw arragement. Castors this end non castors on other end.
This should be a new window, minimise or close it to return to Home Page or press
