A Delicacy from Placentia - Kingmann White MINI-SINE Bar
You have to love the place names the Yanks come up with.
This beauty arrived in today's mail. It has a vee-ed base and a floating magnet that allows it to adhere to both flat and cylindrical surfaces. I reckon its neater than Deckel's Sinuslineal. ( photo supplied in an earlier thread by Gregory Q).
This little 88mm long device may just be my ticket out of the nasty task of calibrating my swivel base. Just set the angle required, clamp it to the work piece or the swivel base and check it with a DTI. Easy. $43 plus $11.60 shipping ex USA.

Hi BT,
Looks great, like all your tools, just two things.
Did you get some guage blocks also? or do you already have then?
I thought the rollers on sine bars needed to be the same size?(thought I have no math to back that up)

Stu,
There is an instruction book. It shows the bar being set with blocks, adjustable parallels, a mic and a height gauge. I do have some blokes but widely spaced ie .100 thou increments, not much use for this application. The sine bars I have seen have equal diameter rollers unlike this one.

Hello Bruce.,
Centre to centre it is 2.500". The large roll is 0.500", the small 0.300". The bar came with a ragged little instruction book which contains about 25 pages of tables giving the required sizes of blocks for 1 minute increments up to 60 degrees. The reduced roll is to allow the use of more convenient sized blocks starting at 0.100"
I have included a few photos of how I can use it on the swivel base for accurate angle set ups in Chris's Dial Indicator thread.

Thank you Bob,
Interesting suggestions for using a mic or height gauge. I guess some blocks and a set of feeler gauges would be a good start. Remember letter and # drill bits too.
Could you make some sort of small jack with as fine a thread as you can to get by till you get more blocks?
A sine bare is pretty high on my list of things to buy.1915 17"x50" LeBlond heavy duty Lathe, 24" Queen city shaper, 1970's G Vernier FV.3.TO Universal Mill, 1958 Blohm HFS 6 surface grinder, 1942 Rivett 715 Lathe, 14"x40" Antrac Lathe, Startrite H225 Bandsaw, 1949 Hercus Camelback Drill press, 1947 Holbrook C10 Lathe.
