|Thread: calculation for a sine bar|
I like a challenge and want to make steps on the arbour for saws as well as gear cutters.I think that a one piece unit will have more rigidity.
Thanks for your confirming my effort ,I can proceed with confidence.
No wonder I can't get my head around trig,The sine bar is 5".
I am going to make an R8 gear cutting arbour and have been trying to work out the packing for a sine bar to set the taper turning attachment.The included angle for the taper is 16.51deg and I have calculated the vertical at 18.23 with trig,.I am not confident that I am correct,could some kind soul give verify this answer please.I havn't done trig since 1964 so remembering is a struggle.

I ordered the metals for Brian Rupnows latest engine design from M-Machine metals and the bearings from bearing boys.The plans were bought from Brian for $25 and were sent to my computer as files his plans are well detailed and descriptive .I built his Rockerblock engine which runs a treat and thought I would have a go at this one.The cost of the metal for a small engine is suprising as I spent 200 pounds including the bearings and I had the brass ,bronze mild steel and silver steel in stock.The cost of building bigger is for me getting prohibitive since retirement .40 years ago I was able to buy brass from a firms scrap box to build clocks for a few quid,how times have changed.

Larry, I think the bracket may be flexing and that a block would give a more consistant result.

compleated 5"*3"*2" block of cast steel on my horizontal small stub miller using a fly cutter with HSsteel tool.It cut the 3" side in one go with shallow cuts and slow feeds and several passes.Milled all round and I was more than a bit pleased at the results as the length was only 1to 2 th out.the ends were spot on and it is square all round.You might think why am I so pleased at this.I bought this miller that had been cleverly converted to a vertical mill by sawing off the bearing housings and planing level and building up with steel blocks bolted to the reduced housings and forming the vertical head on top.I dismantled this down to the reduced housings and formed them as near as possible to the originals as was possible.I have the original cut offs.To be able to fit these new housings I had to make them elongated to allow a fixing below the new ballraced spindle into the holes tapped for the previously alteration through the new oil hole.I made four pulleys with mullty v so they looked like the original flat belt.I used a laser to line up the spindle positions on the blank housings,bored the holes and fitted the new 2morse spindle I made.So you can see this could have been a right cock up.It turned out well.
|Thread: Small skeletonised drill Press|
I have a floor standing tredle drill by Sheane Brothers of Wicklow.It is pictured along side of their lathe,it has two speeds and not one as listed.The belt is round leather and to use the same belt for both speeds one lifts the column allowing the belt to move from small to large pulley.Possibly a 100 years old.
|Thread: Myford Super 7 Lead Screw Not Turning|
Bill I did the same thing and I suspect that you have damaged your half nuts, and that they will need replacing.I was lucky in that a gentleman on this site sold me some new spare nuts that he had.I had had a problem with banding on my work and when I had it serviced they couldn't give me an explanation as to why this was happening.When I replaced the half nuts the banding dissapeared ,so turners that are haveing this problem might have half nuts that want cleaning or replaceing.
|Thread: Myford Super 7|
Geoff,The headstock on the early S7,s has a oil resevoir with a circular sight glass on the front of the spindle if so you have a lathe between 52 and 59 I think and it will have the old clutch.There is a diagram for the clutch on a previous post and as Maurice has said be aware of the double screw .

Brian the mill is featured on the Tony Griffiths lathe site.Look not in the mill section but the lathe section under T&LM Thanks for the interest and stay well.
I have been renovating my small horizontal it's aT&LM and is featured on Tony Griffiths Lathe site It is in the lathe section under T&LM If you want to view it.When it was bought it from a car boot sale it had no spindle so the chap I bought it off converted it to a verticle mill and I bought it for 200 pounds.When I finished my engine I bought another mill and I decided to convert it back to a horizontal mill.I have been finishing off the last bits today.As they cut off the bearing housing I had to make new ones but to be able to attach them I had to make them oval inastead of circular.I made poly v pullys to lolook like flat belt pullys New geat to drive the lever feed ,new lever and new nut,also a new spindle.Also a counter shaft.I am pleased to say it is finished and Tony thinks it might be the only one made between 1914-20.
|Thread: Morse tapers|
Thanks to all who have responded,I can get on with the job now.All of you stay well in these trying times.
Could someone inform me of the height of gauge blocks needed for a 5"sine bar for a 2 morse and 4 morse taper, as I am not makeing much sense of the sine bar calculators on the net.I want to make an angle plate for both tapers so that I can set the bar on my taper turning attatchment.

Nigel have you tried the Burrell museum in Thetford for information on your engine,if it is still there.
|Thread: A sight for sore eyes|
I started work 4/4/61 my 15th birthday and the first job I was given was to move cwt bags of cement.I thought my nuts were in my throat.Getting them of the floor was the worse part,I did get stronger and have carried bricks and blocks on my shoulder all my working life and my right shoulder is 1.5" lower than my left.When out of work I took a job as a malster and malt used to go to the Isle of Jura for whisky on a flat back truck ,The sacks were 18st and one man took them onto his back of the elevator walked forewards and turned and dropped the bags into position until the truck was full.A broken shear pin in the kiln spilt barley into the heat room below and we had to shovel it into 18st bags and carry it up six steps two men lifted it onto my back and I struggled up the steps with assistance from behind we only did this once ,it was to much.A labourer I had worked on a farm and said chick peas were in 21 st bags.I am all for the alteration of the lifting arrangements in the building trade and anyone who hankers after the old ways is barmy.
|Thread: Sieg Mill from ArcEurotrade|
Bought SX3 from ARC 11 years ago and have been delighted with the machine and the service recieved on all queries and items bought over the years.This firm is a model for others.I am only a very satisfied customer.
|Thread: ER collet chuck/mill incompatibility?|
I have an SX3 and the silly hole below the quill are a pain to use .I drilled a hole in the quill and made a c spanner to fit,now I have no problem holding the quill while undoing the collet.It is also handy for turning the qhill when tapping by the use of the c spanner.I can't understand why Sieg didn't do this in the first place.
